基本解釋

When a borehole is full of water, C/O values decrease with increasing borehole diameter or case size.
當(dāng)井內(nèi)流體為水時(shí)，井徑或套管直徑的增大，C/O值減??；
The effect of a sharp change in the borehole diameter, such as that caused by a cave or rugose hole, on an induction log.
感應(yīng)測井中，由于井徑變化引起測量電阻率突然變大的現(xiàn)象。
